DETERMINATION OF THE FIRST 5 CONNECTION OF THE IDENTIFIED GROUND PIN TO THE COMMON GROUND (57) Abstract: A method, device, and electronic signature tool for audio in­ terface self-adaptation. The method comprises: if the absolute value of a voltage difference between first and second pins determined is to be less than a first threshold value, then not executing an identification operation with re­ spect to the first and second pins of an audio interface (S101); if the absolute value of the voltage difference between the first and second pins is determ­ ined to be greater than or equal to a second threshold value, then determining the types of the first and second pins of the audio interface via the positivity/negativity of the voltage difference (S102), where the second threshold value is greater than or equal to the first threshold value; when the absolute value of the voltage difference is determined to be greater than or equal to the second threshold value, and when the voltage difference is posit­ ive, determining that the first pin is a microphone pin and that the second pin is a ground pin (SI03), otherwise, determining that the first pin is the ground pin and that the second pin is the microphone pin (SI04); and, connecting the identified ground pin to a common ground (S105). The detected ground pin connected is to the common ground of an audio signal receiver device to ensure normal communication between an audio signal transmitter device and the audio signal receiver device via the audio interface.
